Peter G. Hammar Peter Gustaf Hammar Sr. was born in Moscow, Idaho in 1935 to Dr. Gustaf Hammar and Louise Blau, both professors at the University of Idaho. The family relocated to Rochester after WWII and Peter remained an area resident most of his life. He graduated from John Marshall High School and Hiram College in Ohio, where he met Mary Ann List and went on to have two children. He taught briefly in Ohio before moving back to Rochester for a 30 year career as a chemistry teacher at Monroe and Franklin in the Rochester City School District. While teaching at Franklin, he met his loving wife, Diane. Peter enjoyed adventures and travels, which included road-tripping with his friend and vacationing in Europe with Diane. One of his favorite pastimes was working on his 1950 Buick, his father's car that he restored from the frame up. He was also a frequent skier throughout his life and made a lot of memories by taking his family on night skiing trips to Bristol Mountain.
